Flow patterns (42-month cumulative)
Inbound (numbers acquired)
| Direct transfer from another RespOrg | 45,507.0 |
| Harvested from disconnect pool | 22,905.0 |
| First assigned from spare pool | 108.0 |
| Reactivated own disconnects | 888.0 |
Outbound (numbers lost)
| Direct transfer to another RespOrg | 88.0 |
| Standard disconnect aging process (3+ months in DISC) | 0 |
| Abbreviated disconnect period (1–2 months in DISC) | 11,939 |
| Released directly to spare pool | 2,992.0 |
Of the 11,939 disconnect episodes this RespOrg has sent through aging, 100% were abbreviated (1–2 snapshots in DISC status). That's a strong early-disconnector signal, this RespOrg routinely releases numbers before the full 3–4 month aging window. Worth checking daily for vanity drops.
Summary
Their website uses flash which obviously isn't supported any more so they are probably so small they don't exist any more but I'll give them the benefit of the doubt and put them in the Small Phone Company category.
